Q-DRFormer: Query-Position Mapping Flow Prediction with Progressive Refinement for Document Rectification

Document image rectification aims to restore images degraded by geometric distortions. Existing U-shaped encoder-decoder methods rely on hierarchical upsampling operations to recover dense flow fields, which provide limited control over the displacement at individual grid positions, leading to spatial inconsistency and...

Phase-Aware Spatial-Frequency Fusion for Few-Shot Fine-Grained Image Classification

Few-shot fine-grained image classification (FSFGIC) aims to classify similar images with limited labeled examples. This work highlights the critical yet underutilized role of phase information in capturing structural relationships within an image. This study introduces a novel plug-and-play amplitude-phase integration...
